Geothermal Technology

How Geothermal Works

Your own backyard has the potential to be an energy source for heating and cooling comfort. Outdoor air temperatures fluctuate throughout the year with the changing seasons. In contrast, ground temperatures about four to six feet below the Earth's surface remain relatively moderate and constant all year. That's because the Earth absorbs 47% of all the heat energy that reaches its surface from the sun. A geothermal system circulates a water-based solution through a buried loop system to take advantage of these constant temperatures. A single piece of equipment has the ability to heat and cool your home, while providing some or all of your home's hot water as well. Geothermal systems can save you 30% to 70% on your monthly utility bills. 

Heating Cycle

During the heating cycle, the fluid circulates through the loop extracting heat from the ground. The heat energy is transferred to the geothermal unit. The unit compresses the extracted heat to a high temperature and delivers it to your home through a normal duct system or radiant heat system.

Cooling Cycle

For cooling, the process is simply reversed. Because the earth is much cooler than the air temperatures on a hot day, the geothermal system removes heat from the home and deposits it into the ground. The fluid is cooled by the ground temperatures and returned to the unit for cooling your home.

Geothermal Loops

Your loop system is the heart of geothermal technology. Regardless of the option you select, it will deliver over 300% efficient comfort and savings for many years into the future. We can help you select the proper loop system based on a site survey and by conducting a detailed energy analysis of your home. Installing a geothermal loop system is like getting a 70% discount on energy for the life of your home.

Vertical Loop: This loop is used mainly when land area is limited and in retrofit applications of existing homes. A drilling rig is used to bore holes at of depth of 150 to 200 feet. A U-shaped coil of high density pipe is inserted into the bore hole. The holes are then backfilled with a sealing solution.

Horizontal Loop: This is the most common loop used when adequate land area is available. Loop installers use excavation equipment such as chain trenchers, backhoes and track hoes to dig trenches approximately 6-8 feet deep. Trench lengths range from 100 to 300 feet, depending on the loop design and application.

Pond Loop: A pond loop is an option if a large body of water is available within approximately 200 feet of the home. A ½ acre, 8 to 10 foot deep body of water is usually adequate to support the average home. The system uses coils of pipe typically 300 to 500 feet in length. The coils are placed in and anchored at the bottom of the body of water.

Open Loop: This system can be installed if an abundant supply of high quality well water is available. A typical home will require 4 to 8 gallons of water per minute. A proper discharge area such as a river, drainage ditch, field tile, stream, pond, or lake must be present. Check your local codes for restrictions before selecting a specific discharge method.

Advantages of Geothermal Energy Systems

Imagine a heating and cooling system for your home that would keep you cool in the summer and warm in the winter, cut your utility bills by 25 to 50 percent, and help save Planet Earth, all at the same time. Sounds like a challenge for the new millennium, doesn't it? This Geothermal advanced heating and cooling system is here today, and thousands of homeowners across the Triangle are already reaping the benefits, including higher comfort levels and lower utility bills.

Lower Utility Bills :

Homeowners with Geothermal units typically realize energy savings of 25 to 50% over conventional gas, oil, or heat pump systems. In fact, a typical 2000-sq.-ft. home can be heated and cooled for as little as $1 a day. In addition, Geothermal systems can supplement the home's conventional water heater, saving up to 30% of hot water costs every year.

Geothermal systems use small amounts of electricity to transfer heat to and from the ground to your home. On average, it can produce four units of energy for every unit of electricity used to power the system. Even the best conventional systems deliver less than one unit of energy for each unit it consumes. Homeowners typically experience an annual savings of 30% to 70% when compared to ordinary systems. Use the Savings Calculator to see how much a geothermal heating and cooling system can save you.

Environmentally Friendly:

Geothermal is recognized by the United States Environmental Protection Agency as the most environmentally-safe, cost effective heating and cooling system on the market. Installing a geothermal system is equivalent to planting 750 trees or taking 2 cars off the road.

Positive Cash Flow:

Geothermal systems have a higher installation cost when compared to conventional systems because of the buried loop system. Some homeowners view the system as being too expensive and fail to see the whole picture. Geothermal will produce significantly cheaper utility bills and annual maintenance costs. The initial cost of a geothermal system can be tied into your monthly mortgage payment or other form of low interest financing option. The savings on your utilities easily cover the increase in your loan payment giving you the extra cash flow. A system will usually pay for itself within a three to five year span.

Free Hot Water Generation:

As a bonus, geothermal systems can produce some or all of your hot water at much higher efficiencies than ordinary methods. A simple connection is made so the geothermal system can deliver hot water to be stored in your hot water heater. In fact, the heat removed from your home during the cooling cycle is deposited directly to the water heater instead of the ground. This provides you with virtually free hot water.

System Life Span:

Ordinary systems require expensive regular maintenance for each unit - the furnace, the air conditioner, and the water heater. When properly installed, a geothermal system requires little or no maintenance beyond periodic checks and filter changes. Equipment life is prolonged since geothermal are located indoors and out of the varying climate and weather. Geothermal systems typically last more than 20 years if properly maintained.

Clean & Safe:

Geothermal units do not use fossil fuels such as natural gas and propane. Threats caused by combustion are eliminated. No worries about flames, fumes, odors, or carbon monoxide.

Improved Comfort:

Geothermal systems heat and cool homes evenly, eliminating the hot and cold blasts of air found with conventional systems. Geothermal also dehumidifies the air during hot summer months.

Quiet:

Geothermal systems use the same principles that operate a refrigerator or freezer, and the units are just as quiet. There is no unsightly outdoor unit to disturb you or your neighbors.
